摘　　要：为了定量分析顺层岩质边坡变形失稳条件,将层状边坡岩体视为理想的弹性薄板,并充分考虑边坡沿走向长度方向的尺寸,采用能量平衡法综合分析顺层边坡岩体稳定性,推导得出边坡变形失稳判据,确定出边坡滑动段与弯曲变形段计算公式,并将所得结果与传统弹性梁理论分析方法进行对比,结合现场实测数据,证明弹性薄板理论分析方法的准确性与适用性。In order to quantitatively analyze the deformation and instability conditions of the bedding rock slope,the layered rock slope is regarded as an ideal elastic thin plate,and the size of the slope along the length direction is fully considered,and the energy balance method is used to analyze the stability of bedding rock slope.The stability of the slope is derived from the deformation and instability criterion of the slope,and the calculation formula of the sliding section and the deformation section of the slope is determined,and the obtained results are compared with the traditional elastic beam theoretical analysis method,the accuracy and applicability of the theoretical analysis method of elastic thin plate are proved.
